Chapter 2 Installation and Wiring





2.1 Exterior Size and Mounting Size (See Appendix 1)

2.2 Mounting Place Requirement and Management

Attention

· Don’t carry the ac drive by its cover. The cover cannot support the weight of the ac drive and may drop. · Please install the ac drive on a strong support, failing which the ac drive may fall off. · Don’t install the ac drive in places where water pipes may leak onto it. · Don’t allow screws, washers and other metal foreign matters to fall inside the ac drive, otherwise there is a danger of fire or damage. · Don’t operate the ac drive if parts are not complete, otherwise there is a danger of fire or human injury. · Don’t install the ac drive under direct sunshine; otherwise, it may be damaged. · Don’t short circuit PB, + and -, otherwise there is a danger of fire or the ac drive may be damaged. · Cable lugs must be connected to main terminals firmly. · Don’t apply supply voltage (AC 220V or higher) to control terminals except terminals TA, TB, TC.

Please mount the ac drive as following application occasions and maintain appropriate condition.

2.2.1 Installation Location

The installation location should meet the following conditions: Good indoor ventilation. Ambient temperature: -10 ~ 40 . If the temperature is higher than 40 , the ac drive should be derating used and forced ventilation is required. Humidity should be lower than 95%, no condensing. Do not mount the ac drive on the timber or other combustible matters. Avoid direct sunlight. Mount in the location free of dust, metal powder, corrosive gas or combustible gas. The installation foundation should be solid and free of vibration. No electromagnetic interference, away from source of interference. Derating use must be considered when the ac drive is installed at high altitude, greater than 1000 m. This is because the cooling effect of ac drive is deteriorated because of the thin air. Derating 6% per 1000 m higher of the altitude.




2.2.2 The Ambient Temperature

In order to enhance operating reliability of the ac drive, be sure where the ac drive mounted has a good ventilation; when the ac drive is used in a closed case, cooling fans or an air-conditioning must be installed to keep the ambient temperature below 40.

2.2.3 Preventive Measures

Installing the ac drive, please set a shield to prevent metal debris falling into it, and remove the shield after installing.

2.3 Installation Direction and Space Ac drives of this series are all equipped fans for forced cooling. In order to be an effective cooling cycle, the ac drive must be mounted in the vertical direction, up, down, left and right away from adjacent articles or baffle(wall) maintain adequate space, as Figure 2-1

2.4.2 Main Circuit Wiring operation

Be sure that the motor is running forward when the running direction command of ac drive is forward. If the motor is running reverse, interchange any two-output terminals (U, V, W) can change the rotate direction of the motor, and you can change function code P2.25 to change phase-sequence of the motor.

Never connect input power supply cables to output terminals, or else parts of the ac drive would be damaged. Do not connect output terminals to earth, be sure output cables not touch to the shell or be shorted, or else the ac drive would be damaged.

Be sure Earth terminal “PE” is connected to earth. The earthling resistance of 380V-class should be below 10Ω. Be sure the earthling not be shared with an electric welding machines or other high-current electrical equipments. Use ground wiring as mentioned in “Appendix 3 Main Circuit Output Cable Selection” and keep the length as short as possible.

When two or more ac drives are used at the same time, do not loop the wires. The right and wrong earthling connection methods are shown as Figure 2-9.

Inverter InverterRight

Fig 2-9 Earthling Connection Method

Attention: The neutral point of motor using Y connection can’t be connected to earth.

Since the ac drive output PWM wave, if a capacitance for improving power factor or a lightning varistor is installed on the output side, which would case tripping or damage to parts, be sure to remove it.

If a contactor or other on-off part is needed to be installed between the output and the motor, be sure the on-off operation is done when the ac drive has no output, otherwise the ac drive would be damaged.

Countermeasures to conduction interference: To inhibit conduction interference of the output, besides installing noise filter and using shielded motor cables, leading all the output cables to earthling metal tube is also a method. Make the distance between the output cables and the control signal cables greater than 30 cm, the effect of conduction interference will obviously decrease too.




Countermeasures to RFI: The input cables, output cables and the ac drive itself would produce RFI. Placing noise filters both at input and output sides, and shielded with metal shell would reduce RFI. The cables between the ac drive and the motor should be as short as possible. Measure to reduce RFI is shown as Figure 2-10.

Fig 2-10 Method to Restrain RFI

Distance between the ac drive and the motor.

The longer the distance between the ac drive and the motor, the higher the carrier frequency would be, and the greater the high harmonic leakage current of the cables would be. Leakage current has a negative impact to ac drives and equipments nearby, so reduce leakage current as little as possible.

The relationship of the distance between the ac drive and the motor and carrier frequency is shown as Table 2-7.

Fig 2-12 35R5GB/37R5PB～3500GB Arrangement of Control Circuit Terminals

In order to reduce interference and attenuation of control signal, the length of control cables should be limited in 50m and away from power cables for more than 30cm. Avoid control wire and power wire being parallel. Try to use STP (Shielded Twisted Pair) to connect analog input and output signal. Function of Control Circuit Terminals

Notes: 1）Dialing SW1, SW2, SW3 to “I” represents current, dialing to “V” represents voltage. 2）Analog input and output signals are easily disturbed by exterior environment, so shielded cables must be used for wiring and the length of the cables should be as short as possible. 3）When an analog output equipment be connected to the ac drive, sometimes because of error act because of interference cased by the analog output equipment or the ac drive, when which happened, a 0.01～0.1uF/50V capacitance or a ferrite bead(enwind 3 laps) could be connected to the analog output equipment.




Wiring of Serial Communication Interface

The ac drive of this series provides standard RS485 serial communication interface for users, which can be composed as master and slave network. By using a host PC or PLC, The ac drive in the network can be monitored in real time and controlled remotely and automatically. Thus more complicated operation control can be realized.

(The Ac drive and Motor are grounded well)

The master can be a host PC or a PLC, the slaves are ac drives of this series. An




RS232/RS485 converter should be installed between the master and the bus when a PC is used. Connect homonymy terminals of the master and slave if the master is PLC.

When several ac drives of S2R4GB～3004GB formed the RS485 network, you should customize the matching resistor of the ac drives on those control panels which are on both ends of the farthest of the bus according to the use.

When several ac drives of 35R5GB/37R5PB～3500G formed RS485 network, you should dial SW4 (double switches) of the farthest ac drive to “ON”, as Figure 2-18.

If the communication still can’t work, then the following actions can be taken:

1）Feed a separate AC supply to PLC (or host PC) and isolate the AC supply;

2）If RS232/RS485 converter is used and the module should be powered by a separate power supply, converter with optical-isolator is recommended;

3）Mount a toroid to the communication cable, or reduce the carrier frequency if the local conditions permit .

Wire Multi-function input terminals

Multi-function input terminals of the ac drive use a full-bridge rectifying circuit. PLC is the common terminal of terminals X1～X8(in S2R4GB～3004GB only X1～X5).

If the ac drive drives an inductive load (such as relay or contactor), then a surge suppressing circuit should be added, such as RC snub circuit, lightning varistor or a flywheel diode (used in the DC electric-magnetic circuit and pay attention to the polarity during installation).Snubbing components should be as close to the coils of relay or contactor as possible.

Notes: ．1 Don’t short circuit terminals 24V and COM, otherwise the control board may be

damaged. ．2 Please use multi-core shielded cable or multi-stranded cable (above 1 mm) to

connect the control terminals. ．3 When using a shielded cable, the shielded lay’s end that is nearer to the ac drive

should be connected to PE. ．4 The control cables should be as far away(at least 30 cm) from the main circuit and

high-voltage cables as possible (including power supply cables, motor cables, relay cables and cables of contactor).The cables should be vertical to each other to reduce the disturbance to minimum.

Keyboard Interface Keyboard Interface of CN3 on the control board uses standard 8PIN interface, which is shown in Figure 2-31. Users can order the extended keyboard cable or make it by themselves according to actual need. Be sure that the extension cable of the keyboard is no longer than 15 meters, otherwise it wouldn’t work properly. (Remove the original keyboard of models of S2R4GB～3004GB, or the exterior can not work properly)

Table 2-9 T568B standard connection



The cables connecting keyboard and control board use standard super-five-class network cable. RJ-45 Interface uses through-line method, namely both sides are connected according to EIA/TIA568B standard. You can make the cable by yourself if you need.

Notes: 1．Both sides of keyboard cable should be connected refer to Table 2-6. Otherwise, the

cable couldn’t work properly or even the keyboard would be damaged. 2．When the keyboard extension cable is longer than 1 m, which must use shielded

twist-pair network cable, RJ-45 interfaces of both sides of the cable should use crystal with shielded metal shell, connect shielded metal shell to shielded layer. Otherwise, it is likely to cause error action because of disturbance.

3．Be sure the extension cable of the keyboard is no longer than 15 meters, otherwise it wouldn’t work properly.

Data-chosen-switch, the default is voltage input. You can refer P4.00～P4.10 to set the range.

2. Max output current of control circuit terminal 10 V is 30 mA. 3. The cable between PLC and 24 V terminals should be connected firmly

(S2R4GB～3004GB should be sure to disconnect the cable JP1 between PLC and 24 V; 35R5GB/37R5PB～3500G should be sure to disconnect the cable between PLC and 24V), otherwise input terminals X1-X8 couldn’t work properly(in



S2R4GB～3004GB only X1～X5).

2.7 Wiring Attention Be sure the input power supply of the ac drive is cut off then you can remove or replace

the motor. Be sure the ac drive has stopped output then you can switch the motor or the power

supply. If a peripheral (brake unit, line reactor, filter) is added, test the insulation resistance of

the peripheral to earth first and be sure the value not below 4 MΩ. Besides shielding the input signal cable and the cable of frequency meter, the cables

should be disposed solely, not parallel with the main circuit cable, and far away from it as possible.

In order to avoid error action caused by molestation, the control circuit cable should use stranding shielded cables, and the wiring distance should be less than 50 meters.

Be sure the shielded layers of shielded cables are not touch other signal cables or shell of equipment, you can use insulating tape to enswathe the bare shielding layer.

The withstand voltage of all the cables should match with the voltage class of the ac drive.

In order to prevent accident, be sure that the control circuit terminal ”PE” and the main circuit terminal “PE” are connected to earth, and the earthling cable can’t be shared with other equipment. The size of main circuit earthling cable should be more than one and a half of the main circuit cable. After completion of wiring, please check whether a cable, a bolt or a connection end .etc., was remained in the ac drive, whether the bolts were fastened firmly, whether the bare cable of terminals were shorted to other terminals.

Chapter 3 Operation


Chapter 3 Operation

3.1 Function of keyboard The keyboards of the ac drive may have different exterior dimensions. However, all of them have the same array of keystrokes and LED display. Moreover, operation and function of them are all the same. Every keyboard has four digitals seven segments LED monitor, nine operation keystrokes, a digital encoder, and eight led indicators (five for status indication and three for unit indication).User can perform function setting, ac drive running, stop, and status monitoring with the keyboard.

DANGER

1, Only turn on the input power supply after replacing the front cover. Do not remove the cover while the ac drive is powered up.

2, When the retry function is selected, do not approach the ac drive or the load, since it may restart suddenly after being stopped.

CAUTION

1, Since the stop key can be disabled by a function setting, install a separate emergency stop switch.

2, Since it is very easy to change operation speed from low to high speed, verify the safe working range of the motor and machine before operation.

3, Do not check signals during operation. 4, All ac drive parameters have been preset at the factory. Do not

change the settings unless it is required. Failure to observe these precautions may result in equipment damage, serious personal injury or death.

3.1.4 Display state of keyboard

The working state of this series ac drive includes two states: stop state and running state.

Chapter 3 Operation


Stop State: If there is no running command input after the ac drive is power on and initialized, or the ac drive has received a stop command input, the ac drive will come into stop state.

Running state: The ac drive has received a running command and then comes into running state.

Therefore, the display states of keyboard include display of stop state, display of running state and display of programming state and display of fault and warning state.

Display of stop state

If the ac drive is a stop state, the four digitals of keyboard will display the parameters value of stop state: For example, the output frequency. See figure-3-2, and the unit

indicator will indicate the unit of the parameter. Press ＞＞

key, the keyboard will cycling display the value of different monitoring objects （selected by the parameter group PC）.

Display of running state

If the ac drive got an effective running command, it will come into running state. Then the four digitals of keyboard will display the parameters value of running state. See example of figure 3-3-3. and the unit indicator will indicate the unit of the parameter.

Press＞＞

key, the keyboard will cycling display the value of different monitoring objects （selected by the parameter group PC）. Fault and warning state If the ac drive has checked out a warning signal, it will come into warning state and show the warning code flickeringly. See example of figure 3-3-5. If the warning signal disappeared, the warning code will automatically disappear. If the ac drive has checked out an error, it will come into fault state and show the fault code steadily. Moreover, the indicator TRIP will light up, see example of figure 3-3-6.

By pressing the＞＞

key, user can view the parameters value of stop state. If you want

to see the details of fault information, press the PRGESC key, the keyboard will go to

programming state, to see the details, please see the parameter values of group PE.

To reset the ac drive, press the STOPRESET key or control terminals or serial communication.

If the fault signal is still exist, the keyboard will keep the fault code displaying and the indicator TRIP lighting.

Figure 3-7 Flow chart of parameter setting Note:

In the function parameter menu, if the display has no flickering number, it means that the parameter cannot be modified. The reasons maybe:

Modifying the value is forbidden because the parameter is actual measure value, or running record value or fixed value. The function parameter cannot be changed when the ac drive is at running state. However, it can be changed at stop state.

So stop the ac drive and then change the parameter value.

Chapter 3 Operation


The ac drive parameters are protected. If function parameter value PF.01=1 or 2, the parameters are forbidden to be changed. This parameter protection function is to avoid operation mistake. To change the protection parameters, change value of function code PF.01 to zero, then all the parameters can be changed.

3.2 Run command mode select The run command modes determine the methods of the ac drive running and stop. The ac drive has three run command modes:

Run command from the keyboard: press the keyRUN

,STOPRESET , to control the ac

drive.

Run command from the control circuit terminals: by using the terminal defined as FWD,REV,COM（2-wire control mode）: FWD, REV, Xi（ 3-wire control mode ）to control the ac drive.

Run command from serial communication: Use a PC or PLC to control the ac drive to run or stop.

Change P0.04 to select serial communication mode. The default setting is Keyboard control mode （The default value P0.04 is 0）, If terminal control mode is needed,

please change the value to 1 or 2. If we want to keep the “STOP/RESET” key STOPRESET

active in terminal control mode, we must set the value to 2. If we need to control the ac drive by PC or PLC serial communication, we should set P0.04 to 3 or 4. If the indicator REMOTE is off, it tells that the ac drive is controlled by the keyboard .If the indicator REMOTE is on, it tells that the ac drive is controlled by the terminals. In addition, if the indicator is flickering, it tells the ac drive is controlled by serial communication.

3.3 Trial Operation

3.3.1 Operation mode of ac drive

This series of ac drive have five operation modes: JOG operation, PID closed loop operation, Wobble frequency operation, PLC programmed operation and common operation.

JOG operation: If the ac drive received a jog operation command （for example,

pressJOG

key） at a stop state, the ac drive will jog running at the jog frequency reference set by function code P2.00～P2.02.

PID closed loop operation: If PID close loop operation is selected by P0.01 (set the value to 9）, the ac drive will chose PID closed loop operation mode. In other word, it will come into PID adjustment as the PID feed and PID feedback. （see parameter group P7）.

Wobble frequency operation: If Wobble frequency operation mode is active （set value of parameter code P0.01 to 10）, the ac drive will come into Wobble frequency operation. The Wobble frequency running parameters can be modified in parameter group P6. By selecting a multi-function terminal and setting the value to 46, connecting the terminal to terminal “COM”, Wobble frequency operation state can be reset （ Refer to chapter 4, see details P3 description）

PLC programmed operation: If PLC programmed operation mode is selected by P0.01 (set the value to 8）, the ac drive will chose PLC programmed operation: every steps can be pre-defined （see parameter group P5 description）. By selecting a multi-function terminal and setting the value to 43, connecting the defined multi-function terminal to “COM”, PLC programmed operation state can be stopped. If the value of a multi-function terminal is 44, connect the defined multi-function terminal to “COM”, PLC programmed operation state will be reset（see parameter group P3 description）.

Common operation modes: in these modes, the ac drive will run at open loop mode. Common operation modes include 7 operation modes, such as keyboard, terminal AI1, terminal AI2, pulse input, serial communication, multi-speed and terminal UP/DOWN operation, etc.

Switch of operation modes of this series ac drive are as figure 3-8 description:

3.3.2 Before operation checkpoints

To ensure safety, prior to initial operation, disconnect the machine coupling so that the motor is isolated from the machine. If initial operation must be performed while the motor is still coupled to the machine, use great care to avoid potentially hazardous conditions. Check the following items before a trial run: Wiring and terminal connections are proper. Wire clippings and other debris removed from the unit. Screws are securely tightened. Motor is securely mounted. All items are correctly grounded. Keyboard Display at Power-Up.

3.3.3 Operation checkpoints

Motor rotates smoothly. Motor rotates in the correct direction. Motor has neither abnormal vibration nor noise. Acceleration and deceleration are smooth. Unit is not overloaded. Status indicator and keyboard display are correct.

3.3.4 A trial run

Please wiring the main circuit and control circuit strictly according to the technology requirement provided by the user manual when the ac drive is ready for operation, turn ON the power supply. Verify that the ac drive powers up properly. If any problems are detected, turn OFF the power supply immediately.

When the keyboard displays the output frequency, the ac drive is initialized. If the keyboard is not connected right, the keyboard will display the fault code “CCF2” after 5 seconds. Please connect the keyboard again.

Operation process of power up the ac drive is as the following:

5.1 Basic Function (Group P0)

P0.00 Reference frequency Range: 0 ～Maximum frequency【0.00Hz】 Note: P0.00 is active when P0.01 or P0.02 is 1, that is, the value can only be adjusted by keyboard digital encoder. P0.00 defines ac drive’s frequency setting value.

Tips: The changed value of P0.00 by keyboard digital encoder will be active immediately. If press "ENTER" key, the value will be stored into the ac drive’s internal EEPROM and will not be lost even power-off the ac drive. When P0.01is set to 1: if P3.12 is set to2, the changed value of P0.00 by keyboard digital encoder will be saved when power loss. Otherwise, the changed value will not be saved . P0.01 Frequency setting 1 Range: 0～10【1】 P0.02 Frequency setting 2 Range: 0～6【0】 0: NULL 1: keyboard digital encoder 2: Terminal AI1 3: Terminal AI2 4: Pulse input 5: Serial communication 6: Multi-step Speed 7: Terminal UP/DOWN 8: Programmable Logic Controller (PLC) 9: PID close-loop 10: Wobble frequency operating Note: When P0.01 is set to use the keyboard for digital frequency settings (P0.01=1),

reference frequency can be adjusted by digital encoder on the keyboard in display status.

Terminal AI1, AI2 is for the analog input signal. Using terminal AI1, AI2, output frequency can be adjusted by 0 ~ 10V voltage signal or 0 ~ 20mA current signal. But it must be based on the type of signal to make correct choice: dial the mode switches on the right place. Please refer to section 2.5 that introduce the control circuit wiring for details.

For details Terminal AI1 (programmable), terminal AI2 (programmable), and pulse input (programmable) refer to explanation of parameter group P4.

Serial communication settings: Users can connect the serial communication port to PC or PLC, then through communication to control the ac drive’s reference frequency.

If P0.01 set to 7, see the description of UP/DOWN in parameter group P3 for details.



P0.03 Frequency setting selection Range: 0～5【0】 0: Frequency setting 1 1: Terminal Selection 2: Frequency setting 1+ Frequency setting 2 3: | Frequency setting 1- Frequency setting 2 | 4: Min(Frequency setting 1, Frequency setting 2) 5: Max(Frequency setting 1, Frequency setting 2)

Note: Frequency settings 1: Frequency set by P0.01 (Frequency setting 1). Terminal Selection: If defined the "FC" function terminals (see P3.01 ~ P3.08), and

the terminal function is effective, P0.02 (frequency setting 2) will be selected as the final frequency setting ; if defined this function terminal but the terminal function is not effective, P0.01 (frequency setting 1) will be selected. If undefined the "FC" function terminal, P0.01 (frequency setting 1) will be the default frequency setting . Frequency setting selection can be switched between the two different signals.

Settings 2 to 5: The final reference frequency value will be decided by frequency setting 1 and frequency setting 2 after the corresponding arithmetic.

Exceptions: If P0.01 is set to 7 (UP / DOWN) or 10 (wobble frequency operating), Setting value 3 to 5 of P0.03 (P0.03=3~5) will be invalid, and setting value 0 will be valid. See terminal UP / DOWN function definition in parameter group P3 and wobble frequency operating definition in parameter group P6 for details. If P0.01 is set to 9 (PID), the analog PID amplitude will be defined by P2.11, when P0.03 is set to 3 to 5 (P0.03=3~5) P0.04 Run command mode selection Range: 0～5【0】 0: Keyboard control 1: Terminal control 1 (STOP invalid) 2: Terminal control 2 (STOP valid) 3: Serial communication 1 (STOP invalid) 4: Serial communication 2 (STOP valid) 5: Terminal control 3 (STOP and JOG invalid)

Note 1: Keyboard control: Control the ac drive Start and Stop by pressing the “RUN” key and

“STOP/RESET ” key on the keyboard.



Terminal control: The user should define X1~X8 terminal to achieve RUN, F/R, FWD, REV, HLD and other running functions(see P3.01~P3.08) first, and then used the terminals to control the ac drive Start, Stop .etc.

Serial communication: Users connected the serial communication port to PC or PLC, then through communication to control the ac drive Start, Stop, F/R and so on.

Note 2: If the “STOP/RESET ”key is valid, users can stop ac drive by pressing

“STOP/RESET ”key on the keyboard for emergency stop. If the “STOP/RESET ” key is invalid, the user can only stop the ac drive by preset control mode.

If P0.04 is set to 5, the JOG key is invalid. If the JOG key is invalid, the user can only start Jog operation by FJOG or RJOG terminal.

In Keyboard and Terminal control mode, communications read and write commands will be ignore.

P0.05 Keyboard direction setting Range: 0,1【0】 0: Forward 1: Reverse

Note: Pressing “FWD/REV” will switch the direction, and change the value of this

parameter P0.05. But the changed direction only take effect currently. Only by changing value of function code and pressing “ENTER” to save the value,

keyboard direction setting will be saved permanently. Direction priority: Terminal set is the highest, second is set by communication,

keyboard is the lowest. If the high one is invalid, the lower priority will take effect.

P0.06 Basic Frequency Range: 0.10～400.0Hz【50.00Hz】

P0.07 Max output frequency Range: MAX [50.00Hz, Frequency upper limit, Reference frequency] ～400.0Hz【50.00Hz】

P0.08 Frequency upper limit Range: Frequency lower limit～Max frequency【50.00Hz】

P0.09 Frequency lower limit Range: 0.00～Frequency upper limit【0.00Hz】 P0.10 Max output voltage Range: 110～480V【Ac drive rated】

Note: Basic Frequency FBASE: Basic operating frequency is the Min output frequency when

the output voltage of ac drive is equal to rated voltage UN. Usually, the motor rated frequency can be treated as basic frequency. The changing range of basic frequency FBASE of this series ac drive is from 0.10 to 400.0Hz. Normally, FBASE is selected based on motor rated frequency. In some special state, FBASE can be set according to



application needed. But at this time, the V/F characteristics of the load and its contributed need must be considered. As shown in Fig. 5-0-1

Max output Frequency

Fig. 5-0-1 V/F characteristic diagram Max frequency FMAX: This setting is the max frequency allowed to be output of this

series ac drive. If reference is bigger than rated value of drive equipment, the motor and equipment may be damaged.

Frequency upper limit fH is the highest frequency that ac drive allowed to work. In addition, frequency lower limit fL is the lowest. Setting frequency upper limit and frequency lower limit, can automatically ensure that the output frequency is’ not higher than frequency upper limit and not lower than frequency lower limit. This function usually used to guarantee motor working in allowed frequency, to avoid mistake action or mechanism or ac drive backfire. It is especially useful in avoid low-speed or over-speed. See P2.04.

Max output voltage is output voltage when the ac drive runs at basic frequency. Usually it is the rated input voltage of motor, which is marked on the nameplate of motor.

P0.11 Step length of digital encoder regulation

Range: 0～250* (0.01Hz/1rpm) 【0】

Note: This parameter is effective for reference frequency and rotate speed of surveillance state online regulating. If P0.11 is set to 0, digital encoder integral regulation function is enabled. That is

keeping on turning digital encoder, the length of every step can rise from 1 to10 and the max 100.

If P0.11 is set to non-zero, fixed-length regulation function is enabled. The value of P0.11 is the step length of digital encoder regulation, which means turning left/right the digital encoder one cycle, the value of reference frequency will decrease/increase ((P0.11)*30).*(0.01Hz/1rmp).

when the adjusting object is reference frequency/ reference speed ,the unit of P0.11 is



0.01Hz/(6/(5*PA.00))r/min; When it is reference speed, the unit is (6/(5*PA.00))r/min under common operation mode and 1r/min under the digital PID control mode.

Example: In the range, when P0.11 is set to 100, turn left/right the digital encoder one cycle, the reference frequency will decrease/increase 30.00Hz and the rotate speed will decrease/increase 900 turns every minute; when P0.11 is set to 10, the reference frequency will decrease/increase 3.00Hz and the rotate speed will decrease/increase 900 turns every minute P0.12 V/F curves setting Range: 0～4【0】

(shadow area is the boost value) Tips:

1. Wrong parameter setting can cause overheat or over-current protection of the motor. 2. When the ac drive drives synchronous motor, torque boost function is recommended



to be used and V/F curve should be adjusted according to the motor parameters. P0.20 Cut-off point used for manual torque boost

Range: 0.00～50.00Hz 【16.67 Hz】

Note: P0.20 defines the cut-off frequency used for manual torque boost to the basic frequency (defined by P0.19), as shown in Fig. 5-0-4. This cut-off frequency is valid for any V/F curve defined by P0.12.

P0.21 Acc time1 Range: 0.1～3600s【6.0s/20.0s】 P0.22 Dec time1 Range: 0.1～3600s【6.0s/20.0s】

Note: Acc time: Acc time is the time taken for the ac drive to accelerate from 0Hz to the

maximum frequency. Dec time is the time taken for the motor to decelerate from maximum frequency.

This series ac drive has defined 4 kinds of Acc/Dec time. Here, only Acc/Dec time 1 is defined, and Acc/Dec time 2~4 can be defined in P2.18～P2.23. You can select different Acc/Dec time by external terminal according to your demand. In addition, you can select different Acc/Dec time in PLC operation.

5.2 Start/Stop Control (Group P1)

P1.00 Start mode Range: 0～2【0】 0: Start directly 1: Brake First and then start at start frequency 2: Speed tracking restart (It is only effective for the motor of 35R5GB/37R5PB or

above) Note: Start directly: Speeds up from zero-speed and accelerate to the preset frequency

within the preset Acc time. Brake first and then start: Ac drive adds some DC injection braking power to load first,

and then startup. As shown in Fig. 5-1-1. Starting mode 1 is suitable for small inertia load which is running forward or reverse while the ac drive is in stop state, such as fan load.DC injection braking parameters refer to P1.03 and P1.04.

Models of 3018G/3022P and aboves can take speed tracking function ; Models of 35R5GB/37R5PB～3015GB/3018Pb need to install a matched speed tracking board if they want to take speed tracking function; Models of 3004GB or below have not this function. P1.01 Start frequency Range: 0.10～60.00Hz【0.50Hz】 P1.02 Start frequency holding time Range: 0.0～10.0s【0.0s】

Note: Start frequency is the initial frequency at which the ac drive starts, see fS as shown in Fig. 5-1-3 ; Holding time of starting frequency is the time during which the ac drive operates at the starting frequency, see t1 as shown in Fig. 5-1-3:

Tips: 1．Starting frequency is not restricted by the frequency lower limit. 2．If reference frequency is lower than starting frequency during acceleration, the ac drive will run at zero-speed.

P1.03 DC injection braking current at start

This value depends on the ac drive model【0.0%】

P1.04 DC injection braking time at start Range: 0.0～30.0s【0.0s】 Note:



P1.03 and P1.04 are only active when P1.00 is set to 1 (start mode 1 is selected), as shown in Fig. 5-1-1.

The range of DC injection braking current and time are dependent on the ac drive model, see Table 5-1-1.

DC injection braking current is a percentage value of ac drive rated current. When the braking time is set to 0.0s, the DC injection braking process will not happen

Model The range of current The range of time G 0.0～100.0% 0.0～30.0s P 0.0～80.0% 0.0～30.0s

Note: Refer to Fig. 5-1-1, the ac drive outputs DC injection braking current at start (P1.03), during DC injection braking time at start.

Tips: If the range of rated current of motor is smaller than the ac drive, this parameter value is suggested to set as: Motor rated current (A) / Ac drive rated current (A) * 100% P1.05 Acc/Dec mode Range: 0～3【0】 0: Linearity 1:S-curve 2: Reserved 3: Reserved

Note:

P1.06 and P1.07 are only active when the Acc/Dec mode is S-curve mode (P1.05=1) and P1.06+P1.07≤90%.

Starting process of S-curve is shown in Fig. 5-1-5 as “①”, where the changing rate of output frequency increases from 0.

Rising process of S-curve is shown in Fig. 5-1-5 as “②”, where the changing rate of output frequency is constant.

Ending process of S-curve is shown in Fig. 5-1-5 as “③”, where the changing rate of output frequency decreases to zero.

Tips: Scurve Acc/Dec mode is suitable for the conveying load such as elevator and conveying belt.

P1.08 Stop mode Range: 0～2【0】 0: Deceleration to stop 1: Coast to stop 2: Deceleration +DC braking

Note: 0: Dec-to-stop

After receiving the stop command, the ac drive reduces its output frequency within the Dec time, and stops when the frequency decreases to zero.



1: Coast-to-stop After receiving the stop command, the ac drive stops output immediately and the load stops under the effects of mechanical inertia.

2: Dec-to-stop +DC injection braking After receiving the stop command, the ac drive reduces its output frequency according to the Dec time and starts DC injection braking when its output frequency reaches the preset frequency of braking. Refer to the Notes of P1.09～P1.12 for the functions of DC injection braking.

DC injection braking frequency at stop is the frequency at which DC injection braking action begins when the ac drive in Dec-to-stop process. In the process of constant rate deceleration, if the output frequency is at or below the “DC injection braking frequency at stop, the DC injection braking function will startup.

DC injection braking current at stop is a relative percentage of ac drive rated current. The DC injection braking function is disabled, when the braking time is 0.0s. The setting range of Type G is 0.0～100.0%, and Type P is 0.0～80.0%.

DC injection braking time is the DC injection braking holding time. This time cannot be set too long; otherwise, it will cause the ac drive overheating. When the DC injection braking time is set to zero, the DC injection braking function is disabled.

Tips: This function will start up after ac drive received stop command. Usually, it is used to improve the stop precision and not for deceleration braking in common running. If faster stop required, braking energy regeneration unit should be fitted, or the ac drive that has the function of brake energy regeneration should be selected.

P1.13 Dynamic braking selection Range: 0,1【1】 0: Dynamic braking is disabled 1: Dynamic braking is enabled

Tips: Only valid to ac drive that power is lower than 15 kW; If set to 1, entering dynamic braking automatically in Dec time would improve control capacity.

P1.14 Voltage of working time of braking Range: 360～750【1 phase:380V

Three-phases: 700V】

P1.14 Utilization ratio of working time of braking Range: 0.0～100.0%【100.0%】

Note: Models power equal to 4kW and below: P1.14 is set as braking point voltage , it

cannot be set too low and need consider the ac drive model.. Models power equal to 5.5kW and above: Resistance and power of the braking

resistor must be taken into consideration when setting this parameter. If set to 5.0%, total DC injection braking time in effect will be equal to 5.0s; Start point of DC injection braking voltage: 710V

P1.15 Trip-free treatment Range: 0～2【0】

0: once trip-free, report Uu1 1: In trip-free time give Uu1 alarm, otherwise report Uu1



2: once trip-free, give Uu alarm

P1.16 Trip-free time Range: 0.5-10.0s【This value depends on the ac drive model】

Note: If having the speed track optional parts, P1.15 could set to 1 or 2. If under voltage occurred in trip-time, the ac drive will display Uu alarm only, and the

motor cannot startup at this time. As shown in Fig. 5-1-7: If under voltage occurred in running, the ac drive will display “Uu” alarm and “Uu1”

fault, as shown in Fig.5-1-7. And PWM output inhibited, motor runs at zero-speed. If the voltage recovered, “Uu” alarm will disappear, If Uu1 fault occurred, the ac drive will stop. If the voltage continues to drop to below 300V, a failure history record or a fault output will not happen. However, if the voltage restored, the system will record the Uu1 fault.

P2.00 is the Jog frequency. Actual Acc time of JOG (t1) can be determined by the following formula. So does the

Note: This function is used to prevent the fluctuations of analog input and reduce the

influence to output frequency. The backlash is 20% of frequency departure setting. P2.06 Carrier frequency Range: 1～16.0kHz Ac drive Power ( kW) ≤11 15～45 55～75 93 ≥110

Note: In order to achieve better control performances, the maximum frequency should not

less than 36 times of the carrier frequency of the ac drive. In order to reduce noise, a higher carrier frequency can be set. If absolute silence is not

The fan always runs when the ac drive is running. After the ac drive stops, the internal temperature detection program will be activated to stop the fan or keep the fan running according to the IGBT’s temperature. If the IGBT’s temperature is over 60°C, the fan will keep running. Otherwise, when the IGBT’s temperature is lower than 50°C, the fan will stop.

The fan operates continuously. The fan operates continuously after the ac drive is switched on.

In other words, the function of terminal is forbidden. To avoid disturbance or mistake action effectively, define the terminals that are not in use as this function 1～5: Operating modes Refer to P3.09 operating modes setup. 6:RST: Reset In fault state, the ac drive can be reset by keyboard by pressing “STOP/RESET ” or by

terminal on or off, if the terminal has been set as RST function. In running state, it can stop the ac drive according to selection of stop mode. RST function is active at the rising edge, so it must be operated as “disabled-enabled-disabled”, shown in Fig. 5-3-1.

7: FC: Setting frequency selection If setting is 7: If P0.03 is set to 1, the operation frequency setting mode can be selected

by FC function terminal. If FC terminal is enabled, frequency setting set will be determined by P0.02 (frequency setting 2); if FC terminal is disabled, frequency setting set will determined by P0.01 (Frequency setting 1). With FC terminal, user can switch the frequency set mode when the ac drive is in running state. This function can make the output frequency control more flexible.

8～9:Jog operation signal (FJOG/RJOG) If setting is 8 or 9, this terminal can enable jog operation, when ac drive didn’t start up

by other running command. FJOG is for jog forward command and RJOG is for jog

10～12: UP/DOWN If P0.03 is set to 2, frequency setting will be the sum of frequency setting 1 and

frequency setting 2. Whether the UP/DOWN terminal is effective or not, the reference frequency will be the sum of initial value of UP/DOWN and frequency setting 2. If any UP/DOWN terminal is effective, the frequency will increase or decrease at the rate of UP/DN rate (P3.10). And the UP/DOWN frequency range will be from the sub of frequency setting 2 and P3.11 to the sum of frequency setting 2 and P3.11. If UP/DOWN function terminal is not effective, the frequency reference of UP/DOWN will keep constant. The frequency reference of UP/DOWN will be saved or not according to the UP/DN reference saving selection P3.12, if UP/DOWN function is not effective and STOP key has been pressed. But if UP/DOWN function is effective, the frequency reference of UP/DOWN will keep the initial value. As shown in Fig.5-3-3.

Note: UP/DOWN Terminal is valid only when P0.01 is set to 7 and the ac drive must be in running state. If frequency setting selection (P0.03) is not 2, the frequency set mode will be

frequency setting mode 1. If frequency setting mode 1 has chosen Terminal UP/DN (setting value is 7) function, whether the terminal UP/DN is effective or not, the ac drive will run at initial value of UP/DN (If the UP/DN reference is lower than zero, the ac drive will run at zero-speed). If any UP/DN function terminal is effective, the UP/DN reference frequency will be changed by terminal UP/DN. And the frequency is increased or decreased on currently operating frequency at the rate of Terminal UP/DN rate setting (P3.10). At this time, if UP/DN is disabled, currently running frequency will be the final UP/DN reference frequency. The frequency reference of UP/DN will be saved according to selection of saving the UP/DN reference if UP/DOWN function is not effective and “STOP/RESET ” key has been pressed. The saved direction is positive. However, if UP/DOWN function is effective, the frequency reference of UP/DOWN will keep the initial value even if press “STOP/RESET ” key. As shown in Fig.5-3-4.

13: FRE Coast-to-stop If the setting value is 13 and the function terminal is effective, the ac drive will stop

PWM output immediately, and exit from running state. Running command is only active after release of terminal FRE. No matter what selection is set to P0.04 (Run command mode selection) and what mode is set to P1.08 (stop mode), the FRE Coast-to-stop function will take effect if the terminal function has been defined and enabled.

37～40: External fault signal / External interrupt signal (normally open / normally close) EH0 - External fault signal normally open / EH1 - External fault signal normally close: External fault command. If the setting is 37-40, the fault signal of external equipment can be input by the terminal. Once the ac drive receives the fault signal, it stops output immediately, and displays last fault code. After the external fault signal is removed, the ac drive needs to be reset before restarting. Tips: Ac drive can’t reset if external fault signal isn’t released. EH0 and EH1 are not influenced by P3.00 (Terminal function mode), Shown in Fig.5-3-6. EI0 - External interrupt signal normally open / EI1 - External interrupt signal normally close: During operating, the ac drive stops its output and runs at zero-speed when it receives external interrupt signal. Once the signal is removed, the ac drive will start and resume normal operation. Please refer to note of EH0 and EH1 above. As shown in Fig. 5-3-6.

Note: For model 3004GB and belows: function code P3.17 is valid for fixed-length

arriving hold time setting. For models above ,P3.17 is the Output function of Relay 2.See description of P3.16 above;

When P3.13=28 or P3.16 =28, the DO or Relay1 output is selected as "fixed-length arriving”, the setting of P3.17 will be effective.

When the P3.17 is set as 0: fixed-length arriving output terminal will hold the output level until the length is reset.

When the P3.17 is set not as 0: the value of P3.17 will be the time during which the fixed-length arriving output terminal will keep the output level .

P3.18 FAR detection width Range: 0.00～10.00Hz【2.50Hz】 Note: This function used to adjust FAR detection bandwidth, when the output frequency

reaches to the reference frequency. The adjusted range is from 0 to ±10.00 Hz of reference frequency. If the ac drive’s output frequency is within the detection width of reference frequency, a pulse signal will be output, as shown in Fig. 5-3-8.

P4.00 Analog Nonlinear Selection Range: 0～3【0】 0: Null 1: AI1 2:AI2 3: Pulse

Note: If the setting is 0, P4.01～P4.05 are used to define AI1 inputs, P4.06～P4.10 are used

to define AI2 inputs, and P4.11～P4.15 are used to defined pulse inputs. They are independent and have no interference with each other.

If the setting is not 0, it will be nonlinear selection, all the parameters from P4.01 to P4.15 are setting points for the selected channel by P4.00. The filter time according to the selected channel setting and the physical value of the others are 0.

If the setting of P4.00 is 1 or 2, the selection will be analog input and the default values to each channel arranged from small to great are: 0.00V, 2.00V, 4.00V, 6.00V, 8.00V, 10.00V;

If the setting is 3, the selection will be pulse input. While the default input to the channel are: 0.00 kHz, 10.00 kHz, 20.00 kHz, 30.00 kHz, 40.00 kHz, and 50.00 kHz. The default physical values are linear relation.

Tips: Only when the value of P4.00 is changed and saved by pressing the “ENTER” key, the input channel value can be initialized to the default value.

Note 1: Min/Max virtual value of analog input is the Min/Max virtual value of the input

signals. If the actual value input is smaller than min value, the min value will be treated as the Min virtual value of analog input. If the actual value input is greater than the max value, the max value will be treated as the Max virtual value of analog input. The max virtual value of analog input must be greater than the min.

Physical value corresponding to virtual value of analog input: The physical value can be reference frequency, rotate speed, or pressure, etc.

The ac drive offers three groups of analog input signal. They are analog input terminal AI1, AI2, and pulse. Users can define input /output curve of each channel. Totally, you can define three curves. The analog input of AI1 and AI2 can be voltage (0～10V) or current (0～20mA),

selected by the switches on the control board.(Switching SW1 at place 1 means OFF, it corresponds to 0-10V. If SW1 is ON, it corresponds to 0-20mA.)

Through setting P4.01～P4.04, P4.06～P4.09 and P4.11～P4.14, can defined two characteristic linear curves. The positive and negative function is shown in Fig.5-4-1.

P4.11～P4.14 are combined for one physical value, which is different to Note 1. User can define their own nonlinear curves by setting these parameters. Six points can be set on the curve. As shown in Fig. 5-4-2. In addition, the setting value to P4.01, P4.03, P4.06, P4.08, P4.11, P4.13 must increase in order.

Note 3:



The input filter time constant is used for digital filter of the input signal, in order to avoid interference of the system.

The bigger the filter time constant, the higher the immunity level and the longer the response time is. On the contrary, the smaller the time constant, the shorter the response time and the lower the immunity level is. If the best setting is not clear, you can adjust setting value according to the status of control stability and response delay time.

P4.16 PG Pulse Range Range: 1～9999【1024】

Note: The setting value of P4.16 (Number of pulses per revolution of PG) is determined by

the characteristic parameters of PG.

Note: The ac drive has two analog outputs（3004GB and the below models as one signal）.

The output can be voltage or current. The full range of voltage is DC 10V and the current is 20mA. You can select what to output, and adjust the range according to your actual need.

The ac drive model of 3004GB and the below models have only one analog channel (AO1).The corresponding P4.18, P4.21and P4.23 all cannot be set.

Note: The ac drive output and instrument systems are likely to produce bias, you can adjust

the output gain (AO1or AO2) for the meter calibration and the change of measuring range.

To avoid fluctuations of output in calibrating, you can make the ac drive output a standard signal (set P4.17 or P4.18 to 5 to get DC 5v. It is 50% of the full range) for AO gain calibration. For example, to calibrate AO1, select the function code P4.22 and press “ENTER” key to enter into the function parameter menu, turn encoder on

the keyboard right +

or left -

to set output signal just to 5 VDC. The modification of P4.22 is valid immediately, and would be saved into P4.22 after pressing ENTER key. To calibrate AO2 is like the above.

If the external instrument has a great bias, the instrument should connect to the ac drive and carry out the actual adjustment.

Note: Record of PLC steps (P5.19) records the steps that the PLC currently operating at. Operating time of this step (P5.20) records the operating time of the step that the PLC

currently operating at. If P5.18 is set to 1, records of PLC steps (P5.19) and operating time of this step (P5.20)

will be cleared , then the value of P5.18 will recovery to 0. Tips:

You can start, pause, and reset of PLC operating by setting external terminal function, which is defined in Group 3.

5.7 Wobble Frequency Operating (Group P6)

P6.00 Wobble frequency operation restart mode Range: 0,1【0】 0: Restart at the freq. and direction before stop, as shown in Fig. 5-6-2. 1: Restart, as shown in Fig. 5-6-3

P6.01 Save wobble frequency operating parameters Range: 0,1【0】 0: not save 1: save

Note: Not save: The ac drive does not save the wobble frequency operating parameters when

power is off and restart when power is on. Save: The ac drive will save the wobble-frequency operation parameters such as the

operating frequency, and operating direction (UP/DOWN) when power is off. The ac drive will restart as the mode defined by P6.00 when power is on.

P6.02 Preset of wobble frequency

Range: The ac drive model of no more than 4kW: 0.00～650.0Hz【0.00Hz】 The ac drive model of no less than 5.5kW: 0.00～400.0Hz【0.00Hz】

P6.03 Holding time before wobble frequency operating Range: 0.0～3600s【0.0s】

P6.04 Wobble frequency amplitude Range: (0.0～50%) of P0.00 【0.0%】 P6.05 Skip frequency Range: (0.0～50%) of P6.04 【0.0%】 P6.06 Skip Time Range: 5～50ms【5ms】 P6.07 Wobble frequency operating cycle Range:0.1～999.9s 【10.0s】

P6.08 Wobble ratio Range: 0.1～10.0【1.0】 Note:



P6.02 is used to define the operating frequency before entering wobble frequency operation mode.

P6.03 is used to define the time when the ac drive operates at wobble-preset frequency.

P6.04 is used to define the range of wobble operating frequency. The actual value is P0.00×P6.04.

P6.07 is used to define a cycle of wobble frequency operation including rising and falling processes.

P6.08 is used to define wobble ratio, which is the ratio of UP time to DOWN time.

P6.09 Random wobble selection Range: 0,1【0】 P6.10 MAX ratio of random wobble Range: 0.1～10【10】 P6.11 MIN ratio of random wobble Range: 0.1～10【0.1】

Note: P6.09 is used to select a fixed wobble ratio value defined by P6.08 or a random value

between P6.11~P6.10. Wobble frequency operation has two starting modes: Auto mode: If the setting of P0.01 is 10, the ac drive will enter wobble frequency

operation mode automatically when power is on. Manual mode: When the setting of P0.01 is not 10, the ac drive first operates at other

defined mode. Then if the multi-function terminal (Xi is set to 45) is valid, the ac drive will enter wobble frequency operation mode.

Distinction: Compared with the auto mode, the manual mode omits the operating at preset frequency.

Wobble frequency operation process: First, the ac drive speeds up to the preset of wobble frequency (P6.02) within the Acc time and then waits for a certain time (P6.03). The ac drive transits to the central frequency within Acc/Dec time, and at last the ac drive operates according to the preset wobble frequency amplitude (P6.04), skip frequency (P6.05), skip time (P6.06), wobble frequency operating cycle (P6.07) and wobble ratio (P6.08) until it receives a stop command and stops within Dec time.

If the frequency setting selected the combination of frequency setting 1 and frequency setting 2, the central frequency will be the sum of P0.00 and frequency setting 2. If not, the central frequency would be the value of P0.00. The wobble frequency operation is shown in Fig.5-6-1.

5.8 PID Control (Group P7)

P7.00 PID feed selection Range: 0～4【1】 0: PID digital input 1: AI1 terminal 2: AI2 terminal 3: Pulse frequency 4: Serial communication

Note: P7.00 is used to define the input method and channel of PID feed. It can be a digital

input (0, 4). It can also be an analog input (1, 2, 3). The digital input is more accurate and stable. Analog input curve can be defined by parameter group P4.

Note: If P7.00 is set to 0, there are 2 kinds of sources for PID digital input: “Analog PID digital feed” (P7.02) and “speed PID feed” (P7.03). If “Feedback selection” (P7.01) is set to 9, “speed PID feed” (P7.03) will be treated as PID digital feed. Besides that, “analog PID digital feed” (P7.02) will be treated as PID digital feed.

AI1/AI2 terminal: PID feed by analog input. Dial the voltage and current switches to select the terminal as a 0~10V or 0~20mA analog input. For details, please refer to the basic operating wiring connections in Fig.2-30 and Fig.2-31.

Serial communication: PID feed will be set by the host PC through RS485 serial communication. If analog PID is used, the setting must be based on the percentage of the measuring range. If speed PID is used, the setting value must be based on the percentage of the largest speed.

P7.01 PID feedback selection Range: 0～9【1】 0: AI1 terminal 1: AI2 terminal 2: Serial communication 3: Pulse feedback 4: |AI1-AI2| 5: Reserved 6: AI1+AI2 7: MIN (AI1, AI2)

8: MAX (AI1, AI2) 9: PG or single-phase speed measuring input

Note: P7.01 is used to define the input method of PID feedback. If P7.01 is set to 9, speed

PID is selected as PID feedback. If the feed is analog input, the analog signal should be set according to full-scale of the maximum speed (The max of signal should be corresponding to the maximum frequency speed). The other setting of P7.01 means analog PID feedback selection.

AI1/AI2, serial communication: The same description as PID feed selection (P7.00). PG or Single-phase speed measuring input: Uses pulse encoder (PG) as the speed PID

control. At this time, terminal X7 or X8 must be set to speed measuring.



|AI1-AI2|: Sub the PID feed analog input signal and the PID feedback input signal, the absolute value is treated as the final feedback value. This function can be used to control temperature difference, pressure difference and so on.

P7.02 Analog PID digital feed Range: 0.0～999.9【0.0】 Note: When analog feedback is used (P7.01=0~8), this function can realize digital setting of

reference by keyboard. The setting must match the range of the actual physical value.

P7.03 Speed PID feed Range: 0～24000rpm【0】 Note: If PG pulse feedback is used (P7.01=9), the speed reference can be set by keyboard. If

the range of speed PID input over 10000, the keyboard will display as “1000”.

P7.05 PID proportional gain (KP) Range: 0.1～9.9【1.0】 P7.06 PID integration time Range: 0.00～100.0s【10.00s】 P7.07 PID differential time Range: 0.00～1.00s【0.00s】

Note: The proportional gain (KP) is the parameter that decides the sensitivity of P action in

response to the deviation. The bigger the proportional gain KP is, the more sensitive the system acts and the faster the ac drive responses. However, oscillation may easily occur and regulation time extends. When KP is too big, the system tends to instability. When KP is too small, the system will slow, and responses lag.

Use integration time to decide the effect of integral action. The longer the integration time, the slower the response, and the worse the ability of control external disturbance variation. The smaller the integration time is, the stronger the integral take effect. The smaller integration time can eliminate the steady state error and improve control precision, fast response. However, oscillation may easily occur, and the system stability decrease, if the integration time is too small.

Differential time define the effect of differential action. The bigger differential time can attenuate the oscillation caused by P action more quickly when deviations occurs and short the regulation time. However, if differential time is too big, oscillation may occur. If the differential time is small, the attenuation effect will be small when deviations occur and the regulation time is longer. Only the right differential time can reduce regulation time.

P7.08 PID delay time constant Range: 0.00～25.00s【0.00s】

Note: P7.08 set the output frequency delay time of PID.

P7.09 Residual margin Range: 0.0～999.9【0.2】



Note: If the residual between feed and feedback value is smaller than residual margin, PID

regulation will stop and the PID output maintain constant. As shown in Fig. 5-7-1. Setting this parameter correctly is helpful to balance the system output accuracy and

stability. The residual margin reduces the regulation accuracy of the system, but improves the system stability, to avoid unnecessary fluctuations of output.

If analog PID is selected, the setting of residual margin (P7.09) is the absolute value of physical value, and it must match the measuring range. If speed PID is selected, the setting of P7.09 is speed. As shown in Fig.5-7-1:

P7.10 PID adjust characteristics Range: 0,1【0】 0: Positive 1: Negative

Note: Positive: When the PID output increases, the output frequency will increase and the

controlled physical value will increase, such as waterworks. Negative: When the PID output increases, the output frequency will increase, but the

controlled physical value will decrease, such as refrigeration system.

P7.11 Integration adjust selection Range: 0,1【0】 0: Stop Integration Adjust when frequency arrive at limit; 1: Continue Integration Adjust when frequency arrive at limit

Tips: For the system that needs fast response, “stop integration adjust when frequency arrives at limit” is recommended.



P7.12 PID preset frequency

P7.13 Hold time of PID Preset frequency Range: 0.0～3600s 【0.0s】 Note: This function can make the PID regulation enter stable state quickly. When the PID operation is start, the frequency will ramp up to the PID preset

frequency (P7.12) within the Acc time, and then the ac drive will start PID operation after operating at the PID preset frequency for a certain time (defined by P7.13).

You can disable the function by setting the PID preset frequency (P7.12) to 0.

P7.14 Analog closed loop measuring range Range: 1.0～999.9【100.0】 Note: This parameter is treated as a benchmark of analog PID feed and feedback. In addition,

it must match the actual measuring range.

P7.15 Enable dormancy Range: 0,1【0】 0: Disable 1: Enable

Tips: There is no standby function when the speed PID feed is used.

P7.16 Dormancy delay time Range: 0～999s【120s】 P7.17 Dormancy threshold Range: 0～Frequency upper limit【20.00Hz】 P7.18 Awakening threshold Range: 0.0～999.9【3.0】

Note:




This function is used to stop the variable pump (auxiliary pumps are all down) when the flow is zero. In this case, if the frequency of variable pump were lower than the “dormancy threshold”, the dormancy delay would be start.

If the frequency is still below the dormancy threshold (P7.17) after the dormancy delay time (P7.16), the variable pump will shutdown. As a result, the entire device is in dormancy state.

To awake the device, the pressure feedback must be reduced to awakening threshold. Then the variable pump would startup. As shown in Fig.5-7-3.

5.9 Fixed-length Function (Group P8)

P8.00 Preset length Range: 0.000～65.53 m 【0.000m】 P8.01 Actual length Range: 0.000～65.53 m 【0.000 m】 P8.02 Rate of length Range: 0.001～30.00 【1.000】 P8.03 Correction Coefficient of length Range: 0.001～1.000 【1.000】 P8.04 Shaft Diameter Range: 0.01～100.0 cm 【10.00 cm】 P8.05 Deceleration point Range: 50～100 % 【90 %】 P8.06 Deviation value Range: -200.0～200.0 mm 【0mm】

Note: This group of parameters is used for function of stop at fixed length. The ac drive inputs counting pulse by terminals (the ac drive models of no less than

5.5kW: X7 or X8 is defined as function 55, or X7 is defined as function 56 and X8 is defined as function 57; the ac drive models of no more than 4 kW: X4 or X5 is defined as function 55, or X4 is defined as function 56 and X5 is defined as function



58 ), and calculates length according to PG Pulse Range (P4.16) and Shaft perimeter (P8.04).

Calculated length ＝ Number of count pulses /PG Pulse Range (P4.16) *shaft perimeter (P8.04)

The calculated length can be corrected through P8.02 (Rate of length) and P8.03 (correction coefficient of length), and the actual length is the corrected length.

Actual length ＝calculated length *Rate of length/ correcting coefficient of length

If the actual length (P8.01) is less than and nearly to the preset length (P8.00), the ac drive will decelerate and run at low speed automatically. When actual length (P8.01) ≥ preset length (P8.00), the operating frequency will be zero, and the ac drive will stop according to the stop mode. When the ac drive restarts, it needs to clear the actual length or increase the preset length. The preset length (P8.00) must be larger than the actual length (P8.01)), otherwise, the ac drive will not start. As shown in Fig.5-8-1.

We can adjust the initial deceleration time of the ac drive through setting the deceleration point, reducing the deceleration point appropriately when the ac motor inertia is large, thus the motor will decelerate ahead of schedule. At the same time by setting the slide (P0.09 lower frequency limitation) to adjust the frequency and deviation (P8.06). When the ac motor is overshoot, set P8.06 negative; and if it cannot reach the setting then set P8.06 positive. Now suppose that one motor is overshoot, after doing the corresponding parameter settings, the running process is as shown in Fig.5-8-2.

Tips: The actual length can be cleared by multi-function input terminal (Define terminal Xi as No.52 function). The actual length will be calculated only after this terminal is disconnected. Actual length (setting of P8.01) will be saved automatically when the power is off. If the operation frequency is greater than frequency upper limit and no pulse is input after the running time is longer than 30 seconds, the ac drive reports pulse coder fault (dE) when actual length is 0. If P8.00 is set to 0, function of stop at fixed length is disabled, but the calculated length is still effective. The setting value must increase 200.0mm when P8.06 is modified by MODBUS communication. The corresponding relation between communication value and actual used value (which can be displayed on the keyboard) is as follows: Reality used value (displayed on the keyboard)) = Communication setting – 200.0mm

P9.00 Gain of slip frequency compensation Range: 0.0～200.0%【0.0%】 P9.01 Slip compensation time const Range: 0.01～2.55S 【0.20S】

Note: The motor’s slip changes with the load torque, which results in the variance of ac

motor speed. The ac drive output frequency can be adjusted automatically through slip




compensation according to the load torque. Therefore, the electrical characteristics of the mechanical hardness are improved. As shown in Fig. 5-9-1.

Synchronous speed

Freq. aftercompensation Compensation Freq. Δf

Load torque Fig. 5-9-1 Auto slip compensation diagram

In rated torque state, the value of slip compensation is: Gain of Slip Frequency compensation (P9.00) × Rated slip (Synchronous speed- Rated speed)

Electro motion state: Increase the gain of slip compensation (P9.00) gradually when the actual speed is lower than the reference speed.

Generating state: Increase the gain of slip compensation (P9.00) gradually when the actual speed is higher than the reference speed.

Tips: The value of automatically slip compensation is dependent on the motor’s rated slip; therefore, the motor rated speed (PA.08) must be set correctly. Slip compensation is disabled when Gain of slip compensation is set to “0”.

P9.02 Energy saving control selection Range: 0,1 【0】 0: Disabled 1: Enabled

Note: The energy saving control parameters have been preset at the factory to the optimum

values. It is not necessary to adjust them under normal operation. If your ac motor characteristic has great difference from those of standard induction motors, refer to the following description to adjust the parameters.

P9.03 Energy saving gain coefficient

Range: 0.00～655.3 【This value depends on the ac drive model】

Note: The energy saving gain coefficient used in the energy saving control mode is for

calculation of the voltage at which motor efficiency will be the greatest, and set the voltage as the output voltage reference. The value of P9.03 is preset according to the standard induction ac motor before delivery. When the energy saving gain coefficient increases, the output voltage will increases.



P9.04 Energy saving voltage lower limit(50Hz) Range: 0～120% 【50%】 P9.05 Energy saving voltage lower limit(5Hz) Range: 0～25% 【12%】

Note: These parameters are used to set the lower limit of output voltage. If the voltage

reference value calculated in the energy saving mode is smaller than the energy saving voltage lower limit, the energy saving voltage limit will be treated as the output voltage reference. To prevent the motor stalling at light loads, the energy saving voltage lower limit must be set. Set voltage limits at 5Hz and 50Hz; the setting value is obtained by linear interpolation if the frequency is out range of 5Hz to 50Hz. The setting value is made by the percentage of motor rated voltage.

In the energy saving control mode, the optimum voltage is calculated according to load power, and the voltage is supplied to the load. However, the set parameter may vary because of temperature variations or using various manufacturers’ motors; therefore, the optimum voltage may not be supplied in some cases. Automatic fine-tuning control voltage maintains highly efficient operation.

P9.06 Time of average power Range: 1～200*(25ms)【5】

Note: Preset the time of average power calculating in energy-saving control mode. The

setting range of P9.06 is 25ms×(1～200).

P9.07 AVR function Range: 0～2【2】 0: Disabled 1: Enabled always 2: Disabled in decelerating process

Note: AVR means automatic output voltage regulation. When AVR function is invalid, the

output voltage will fluctuate when the power supply voltage fluctuates. When it is valid, the output voltage would not fluctuate as the input voltage. The output voltage



will keep constant within the ac drive output capacity.

P9.08 Over modulation enable Range: 0, 1【0】 0: Disabled 1: Enabled

Note: When the over modulation function is enabled, the ac drive voltage output capacity

can be improved. However, if the output voltage is too high, the output current harmonics will increase.

P9.09 Drop control (load distribution) Range: 0.00～10.00Hz【0.00Hz】

Note: When several ac drives drive one load at the same time, the function will make the ac

drives share the load equally. When the load current of one ac drive is greater (>50%), this ac drive will reduce its

output frequency to shed part of the load according to the settings of this parameter. Once the load current is below 50% (<=50%), the ac drive will stop reducing its output frequency. If the load current has been greater than 50%, the output frequency reduces until the difference between reference frequency and P9.09.

Tips: Slip compensation and drop control cannot be used at the same time. Slip compensation has a higher priority.

5.12 MODBUS Communication (Group Pb)

ALPHA 6000 can perform MODBUS communication with a programmable controller (PLC). The MODBUS network is composed of a master PLC and 1 to 31 (maximum) slave ac drives. The master always sends message to slave and the slave responds to master.

The master can send a message to an addressed slave unit at a time. Therefore, address numbers are assigned to each slave unit in advance and the master unit specifies a number to perform signal transmission. The slave unit, which receives the command from the master unit, executes the function and returns the response to the master unit.

Communication Specifications

Interface: RS-485

Synchronization: Half-duplex asynchronous.

Transmission parameters:

Baud rate: Selectable from 1200, 2400, 4800, 9600, 19200, 38400 BPS (parameter Pb.00)



Data length: fixed at 8 bits

Parity: even parity/no parity/odd parity selectable (parameter Pb.02)

Stop bit: fixed at 1 bit

Protocol: In accordance with MODBUS

Maximum number of units to be connected: 31 units (when RS-485 is used.)

Data to be sent or received by Communication

Data to be sent or received by communication include run commands, frequency reference, fault contents, ac drive status and parameter writing/reading. It is need not to set parameter, you can read monitor content and write function parameter.

Select “serial communication” in parameter P0.01 (Frequency setting 1, P0.01=5) or P0.02 (Frequency setting 2, P0.02=5), and then the frequency setting command can be provided by PLC. Writing the value of frequency setting in special register (002H) can set frequency setting, which is not saved after power off. Or set P0.01（or P0.02） to 1 modify the value of P0.00 by communication to come true frequency setting.

Set the operating control method in parameter P0.04 to “Serial communication 1(STOP invalid)” (P0.04=3) or “Serial communication 2(STOP valid)” (P0.04=4). Then the operating command can be provided by PLC;

If the setting value of P7.00 is 4 (Serial communication), the PID feed can set by PLC; If the setting value of P7.01 is 2 (Serial communication), the PID feedback can set by PLC.

If serial communication is selected as the frequency setting or run command, then the commands of reading the running status of ac drive, writing run command or reading/writing parameters are all valid. If frequency setting is set to “serial communication”, frequency command can be preset by communication; if run command mode is set to “serial communication”, the running command send by communication will be effective. If you want both frequency command and running command valid, you must select “serial communication” in frequency setting (1 or 2 in parameter P0.01 or P0.02) and run command mode (3 or 4 in parameter P0.04).

Pb.00 MODBUS Baud rate selection Range: 0～5【3】 0:1200bps 1:2400 bps 2:4800 bps 3:9600 bps 4:19200 bps 5:38400 bps

Pb.01 MODBUS slave address Range: 0～31【1】

Note:



The slave address number is set. It is necessary to set the address number so that it will not overlap with the address numbers of other slaves in the network. To make many ac drives and control PLC operate in the network, every ac drive has its own address number. At most 31 ac drives whose address numbers are from 1 to 31can tie to control PLC at the same time. 0 is broadcast address. The slave does not receive communication command when Pb.01 is set to 0.

Pb.02 MODBUS parity selection Range: 0～2【0】 0: Even parity 1: Odd parity 2: No parity

Pb.03 MODBUS time over detection Range: 0～100.0s 【0.0s】

Note: If Pb.03 is set to zero, this function is disabled. If Pb.03 is not set to zero, overtime detection is enabled. And the detecting time is the

setting value of Pb.03. If in detecting time, abnormal data is be sent or received, the ac drive will stop immediately and display EF0. It need to manual reset.

Tips: If in detect time the slave just receive abnormal data, it will stop and display EF0.

Pb.04 Response delay time Range: 0～500ms【5ms】 Note: It refers to the time from ac drive receiving the host PC command to returning

response frame to it.

Pb.05 MODBUS frequency reference unit Range: 0,1【0】 0:0.01Hz 1:0.1Hz

Note: Used to select the frequency unit of communication command. The output frequency resolution of this series ac drive is 0.01Hz. If the frequency

reference unit is set to 0.01Hz in parameter Pb.05 (Pb.05=0), the unit of the received frequency reference will be treated as 0.01Hz. If Pb.05 is set to 1 (0.1Hz), the unit of the received frequency reference will be treated as 0.1Hz and the value will be automatic transferred to 0.01Hz internally. For example, if the frequency command is 01F4H (the hexadecimal value of 500), it will be treated as 5.00Hz when Pb.05 is set to 0. Or it will be automatic transferred to 50.0(0) Hz and treated as 50.00 Hz when Pb.05 is set to 1.

Pb.06 Selection of MODBUS data storage Range:0,1【0】 0: Not save to EEPROM 1:Directly save to EEPROM

Note:



This function code is used to select whether to save the MODBUS data to EEPROM or not. If pb.06 is set as 1, parameters that modified by MODBUS communication will be saved to EEPROM directly. However, if Pb.06 is set as 0, the modified parameters will not be saved to EEPROM, but stored in RAM and they will be lost when power is off. The other method to save the data to EEPROM is that write the MODBUS address corresponding to the modified parameter to 0x00FF, then the data will be saved to EEPROM which acts as the “ENTER “key to save the data.

Write or erase EEPROM frequently will reduce the life of EEPROM. Write parameter data and save the data to EEPROM frequently in communication mode is not allowed; for writing data frequently, you must modify Pb.06 as 0.

Pb.07 CCF6 Fault Handling Range:0,1【0】 0: Not generate fault and keep on running 1: Generate fault and stop

Note: This function code is used to decide whether to generate communication fault or not. When the value is 1, if communication fault occurs, the keyboard will display CCF6 and the ac drive stop as fault occurs; when the value is 0, it doesn't generate the fault and the ac drive will keep on running.

PC.19 Actual length (m) Range: 0,1【0】 0: No display 1: Display

Note: If PC.19 is set to 1, the actual length will be displayed in monitoring state, and all unit

indicators will be off. If it is set to 0, actual length will not be displayed.

PC.20 Power on display Range: 1～19【1】 PC.20 is used to set the first display parameter at power on. The setting value is from 1

to 19, corresponding to PC.01~PC.19 respectively. If the display property of the first display parameter is 0 (PC. XX=0, XX is the value of PC.20), the keyboard will search from the current settings of PC.20 (PC. XX) to the last (PC.19) and then back to go on search from 1 (PC.01) to the value of PC.20, until the setting value is 1. In addition, keep this display object as the first monitoring object.

Power on display selection will take a priority display of PC.01 ~ PC.19 absolutely; and only takes affect at the boot time. When there is an error, an alarm or a communication CALL to be displayed, the error will display at first, then the alarm or the CALL, and the power on display selection will not work.

PC.21 Rotating speed display coefficient Range: 0.1～999.9%【100.0%】

Note: PC.21 (Rotating Speed display coefficient) is used to correct the bias of displayed

rotating speed and it has no influence on actual speed. Rotate speed = actual rotate speed × PC.21 (PG) Rotate speed=120 × Operating Frequency ÷ PA.00 × PC.21 (non-PG) Reference speed= PID reference speed × PC.21 (PG) Reference speed=120*reference frequency÷PA.00×PC.21 (non-PG)

PC.22 Linear speed display coefficient Range: 0.1～999.9%【100.0%】 Note: PC.22 (Linear speed coefficient) is used to correct the bias of displayed line speed and

it has no influence on actual speed.

5.14 Protection and Fault Parameters (Group Pd) Pd.00 Motor overload protection mode selection

Range: 0～2【1】

0: Disabled 1: Common motor (with low speed compensation) 2: Variable frequency motor (without low speed compensation)

Note: Disabled

The overload protection is disabled. Be careful to use this function because the ac drive will not protect the ac motor when overload occurs;

Common mode (with low speed compensation) Since the cooling effects of common motor deteriorates at low speed (below 30 Hz), the motor’s overheat protecting threshold should be lowered, which is called low speed compensation.

Variable frequency motor (without low speed compensation) The cooling effects of variable frequency motor are not affected by the motor’s speed, so low speed compensation is not necessary.

Pd.01 Electro-thermal protective value Range: 20～110%【100%】 Note: In order to apply effective overload protection to different kinds of motors, the Max

output current of the ac drive should be adjusted as shown in Fig.5-13-1.

Motor overloadprotectivecoefficient

Fig. 5-13-1 Motor overload protection curve

Motor overload protection coefficient calculates:

Motor overload protection coefficient =the max allowed current of load/rated output current of ac drive*100%

Generally, the Max load current is the ac motor rated current. If the motor heat resistance is better, the value can be increased properly on the basis (for example, 10%). On the contrary, if the motor has worse heat-resistance, the value should be decreased some.

Tips: If the motor rated current does not match that of the ac drive, motor overload protection can be realized by setting Pd.01. If overload protection happened, the ac drive will stops PWM output and display OL1 .

Pd.02 Pre-overload detection level Range: 20.0～200.0%【160.0%】 Pd.03 Pre-overload detection time Range: 0.0～60.0s【60.0s】

Note: Pd.02 defines the current threshold for overload pre-alarm protection. The setting

range is a percentage value of rated current. Pd.03 defines the time during which the ac drive current exceeds Pd.02. If the

pre-overload status remains after this period, the ac drive will output pre-alarm signal (OLP2).

Overload pre-alarm take effect means that the ac drive current has exceeded Pd.02 and the Pre-overload time exceeded Pd.03.



ActionDetect time Detect time

Detect thresholdOutput current

EnabledTime

Time

Fig. 5-13-2 Overload pre-alarm function

Tips: 1. Pre-overload detection threshold should be lower than the overload protection

threshold. 2. During the overload detection time, if the current of ac drive is less than Pd.02, the

ac drive will clear the record of pre-overload detection time.

Pd.04 Current amplitude limit Range: 0～2【1】

Pd.05 Current amplitude limiting level Range: Type G: 80～180%【150%】 Type P:60～140%【120%】

0: Invalid 1: Valid during Acceleration and deceleration, invalid in constant speed Operation 2: Valid

Note: When the ac drive is running at Acc/Dec or constant speed, there may be a sharp

increase in the current, because of the unmatched of acc time and motor inertia, or the mutation of load torque. In order to control the output current, when Pd.04 is set to 1 or 2, the ac drive’s output frequency may be adjusted automatically.

In Acc or Dec process, if the output current reaches “Current amplitude limiting level” (Pd.05), the ac drive’s output frequency will stop changing until the current returned to normal, and then continue accelerating/decelerating. Finally, the current will be controlled not more than Pd.05.

In constant speed operating process, if Pd.04 is set to 2, when the output current reaches “Current amplitude limiting level” (Pd.05), the ac drive will reduce output frequency. When the current lower, the ac drive will return to the original work state. If Pd.04 is set to 1, the output frequency will not be changed.

When the ac drive is in the status of current amplitude limit, the time last more than 1 minute or press “STOP/RESET ”key directly and hold over 2s, the ac drive will coast to stop.

Pd.06 Over-voltage at stall function selection Range: 0,1【1】

Pd.07 Over-voltage point at stall Range:120.0～150.0%(Bus voltage)【140.0%】

0: Disabled (The proposed option, when braking resistor is mounted) 1: Enabled

Note: During deceleration, the motor’s decelerate rate may be lower than that of ac drive

because of the load inertia. At this time, the motor will feed the energy back to the ac drive, resulting in the voltage rise on the ac drive's DC bus. If no measures taken, the ac drive over voltage fault will happen.

If Pd.06 is set to 1 and enabled, during the deceleration, the ac drive detects the middle direct voltage and compares it with the over voltage point at stall defined by Pd.07. If



the middle direct voltage exceeds the stall over-voltage point, the ac drive will stop reducing its output frequency. When the middle direct voltage becomes lower than the point, the deceleration continues.

When the ac drive is in the status of over-voltage at stall, the time last more than 1 minute or press “STOP/RESET ”key directly and hold over 2 seconds, then the ac drive will coast to stop.

Pd.08 Input phase loss detection level Range:1～100%【100%】 Pd.09 Input phase loss detection delay time Range: 2～255s【10s】

Note: Input phase loss detection function can detect loss of input phase or a serious

imbalance in the three-phase input, in order to protect ac drive. If the input phase loss detection is hypersensitive, you can appropriately increase the detection level (Pd.08) and detection delay time (Pd.09). Conversely, decrease the detection level (Pd.08) and detection delay time (Pd.09).

Pd.10 Output phase loss detection level (SPO) Range: 0～100%【0%】 Pd.11 Output phase loss detection delay time Range: 0.0～2.0s【0.2s】

Note: Output phase loss detect function can detect loss of output phase or a serious

imbalance in the three-phase output, in order to protect ac drive and motor. If the detection of output phase loss is hypersensitive, you can appropriately decrease the detection level (Pd.10) and increase the detection delay time (Pd.11). Conversely, increase the detection level (Pd.08) and decrease detection delay time (Pd.09).

Pd.12 Enabling keyboard keys UP/DN Range: 0,1 【0】



0: Invalid 1: Enabled Note: In the digital encoder damage cases, set Pd.12 to 1, so “JOP” key can be used as

UP and direction key can be used as DN, or press “＞＞+JOP” key and hold 5 minutes, then the function will be enabled.

Pd.13 AE1, AE2 Alarm choice Range: 0,1 【0】 0: Not show alarm 1: Display alarm

Note: The function is used to decide whether need to display alarm when analog signal is abnormal

Pd.14 Auto reset times Range: 0～10【0】 Pd.15 Reset Interval Range: 2.0～20.0s every time【5.0s】

Note: It means there is no auto-reset function when auto reset times is zero. Only three

faults: OC, OU and GF can be auto reset. Auto reset function can reset these three faults in preset times (Pd.14) and interval

(Pd.15). During the reset interval, the ac drive stops output and runs at zero-speed. It will restart according to start mode after reset. When Pd.14 is set to 0, it means “auto o\reset” is disabled and the protective function will be activated in case of fault.

Tips: Be careful in using auto-reset function, otherwise human injury or material loss may occur. SC fault need 10 seconds waiting time for manual reset.

5.15 Running History Record (Group PE)

PE.00 Type of latest fault Range: Table 5-14-1【NULL】 PE.01 Output frequency at last fault Range: 0~Frequency upper limit【0.00Hz】 PE.02 Reference frequency at last fault Range: 0~Frequency upper limit【0.00Hz】 PE.03 Output current at last fault Range: 0~2 times of (rated current)【0.0A】 PE.04 DC bus voltage at last fault Range: 0~1000V【0V】

Note: If faults occur during operating, the ac drive stops PWM output immediately, and

accesses to the fault protective state. Moreover, the fault indicator “TRIP” is lit up and flickered. The operating condition (such as output frequency, reference frequency, output current, and DC bus voltage etc.) of latest fault and types of the last 3 faults



(FL.14~FL.16), could see in PE.01~PE.08. Descriptions of faults are shown in Table 5-14-1:

Note: “Total Operating time” (PE.09) records the actual operating time from first use of the

ac drive to present. “Total Power On time” records the actual time that the ac drive is power-on from first

power on to present. “Total electric-consumption (MWh)” records the high 16 bits of ac drive’s total

electric--consumption. “Total electric-consumption (KWh)” records the low 16 bits of ac drive’s total

electric--consumption.

5.16 Protection of parameters (Group PF)

PF.00 User password Range: 0～9999【0】 Note: User password setting: The initial value of user password is 0, which means the

password protection function is invalid. At this state, user can access all parameters and parameters content of Group PF.

Unlock the user password: If the user password is effective, the preset password is required to access Group PF. Otherwise, no parameters of Group PF can be accessed.

Changing the user password: If password protection function is effective, right password must be input first to unlock. After unlocking, select PF.00, re-change this parameter value, and press “ENTER” to save the value. Now, the password changing is completed. Before changing the user password, remember to set PF.01 to 0, so that all parameters are allowed to be changed.

Tips: The password will become effective when you press“PRG/ESC” to exit from Group PF if you set user password. Please remember the password, otherwise, you will have no access to all parameters of Group PF. If you forget user password, please contact with manufacturer,



Example: Set the password to 1234, then exit from Group PF and unlock the user password. The process is shown in Fig. 5-15-1 and Fig. 5-15-2.

PF.01 Parameter write-in protection Range: 0～2【0】 0: All parameters are allowed changing; 1: Only setting frequency (P0.00) and PF.01 can be changed; 2: Only PF.01 can be changed.

Note: PF.01 is set to 0: All parameters are allowed to be changed But only the parameters,

which are marked “” in function table, can be changed no matter what the ac drive is running or not. The parameters, which are marked “×”can be only changed when the ac drive is in stop state. Other parameters cannot be changed. About the changeable of parameters, refer to Chapter 4 for details. In addition, you can examine the parameters display on keyboard. If any digit of the parameter is flashing, the parameter is allowed to change. If none digit of the parameter is flashing, it cannot be changed.

PF.01 is set to 1: Only P0.00 and PF.01 can be changed; PF.01 is set to 2: only PF.01 can be changed.

Tips: If PF.01 is set to 0 (all parameters are allowed changing), reference frequency, speed PID input, and analog PID digital input can be adjusted and saved online in parameters monitoring status. If PF.01 is set to 1, only reference frequency can be adjusted online. If PF.01 is set to 2, All online adjusting are disabled.

PF.02 Parameter initialization Range: 0～2【0】 0: No operation 1: Clear fault history 2: Restore to defaults (except records and password).

Note: PF.02 is set to 0: No operation. PF.02 is set to 1: When PF.02 is set to 1, the fault records of PE.00~PE.08 will be

cleared in favor of faults debugging and analyzing. PF.02 is set to 2: If PF.02 is set to 2, the parameters (except running history and user

password) are restored to defaults. Tips:

If user forget the setting value of parameters, and do not want to set them one by one, setting PF.02 to 2 can be used to rapidly restored to defaults, in favor of parameters resetting. PF.02 will be restored to 0 automatically after clearing the fault records or restoring to



defaults. This means operation has already been finished.

PF.03 Parameter copy Range: 0～3【0】 0: No action 1: Parameters download 2: Parameters upload 3: Download parameters except motor’s

Note: PF.03 is set to 0: No action; When PF.03 is set to 1 (Parameters download), the copied parameters stored in the

keyboard will be download to the ac drive. If PF.03 is set to 2 (Parameters Upload), all parameters set by user in ac drive will be

copied to EEPROM on keyboard. If PF.03 is set to 3, the rated parameters stored in the keyboard except motor’s will be

cope to ac drive.

Tips: When ac drive is working in the same application, using this function can quick copy the set parameters, and shorter the time spent on debugging and maintenance. PF.03 is only valid for LCD keyboard. Parameter copy is only effective to LCD keyboard. PF0.3 will be set automatically to 0 . At present, only 35R5GB/37R5PB ac drive and above models can match LCD keyboard, but parameter copy of LCD keyboard is not open at now.

0: Type G (Constant torque) 1: Type P (Inlet fan and pump series loads) Note: The parameter is only valid to the ac drive of G/P series, otherwise it is always 0. Default value of the ac drive is 0. If want type P, please setting PF.04 to 1. Example: When the ac drive model is type G (such as 31R5GB), you want the ac drive

of 32R2PB (Type P), set PF.04 to 1. Tips: By this way, you can get a type G ac drive from a type P ac drive.

Chapter6 Troubleshooting


Chapter 6 Troubleshooting

6.1 Troubleshooting When the ac drive has detected a fault, the keyboard will display the fault code, and the ac drive will stop PWM output and come into fault state. In the fault indicator TRIP will flicker, the fault relay will output the programming function and the motor will coast to stop. At this time, you should find the reason of fault and apply corrective actions. If the listed troubleshooting cannot solve the problem, please contact our company directly.

After debugging, you can press STOPRESET or replace external terminals to restart the ac

drive. Attention: the ac drive can’t startup even through debugging has been finished if operating signal isn’t removed, you should cut operating signal first and then close again or remove main circuit power supply once to make the fault reset. If the SC fault appeared, the replacement is only permitted after 10 seconds. If you want to see the work condition (such as output frequency, reference frequency, output current, bus voltage.,

etc) or contents of the latest three fault, please press PRGESC to enter into program state

If a high-level of EMI is expected and CE, UL, CSA standards are required or when weak noise resistance equipment is installed around the ac drive, please fit noise filter in the system. The wiring cables should be as short as it can be and the filter should be





closer to the ac drive. The grounding of the filter should not employ thin and long wire, but directly connect the filter housing to the back plate of metal case where the paint has been scraped off. This grounding method through surface contacting can effectively reduce the HF grounding resistance, and the filter is capable of maximizing its potential effect.

7.2.3 Brake unit and resistor

The ac drive series of 3015GB/3018PB and the below models have built-in brake function. If users want to increase their brake torque, the only thing to do is to mount external brake resistor. Built-in brake function isn’t applied for 3018G/3022P and above models. If users want to increase the system brake torque, external brake unit should be mounted. The brake unit includes brake control, drive and the discharge part of the resistance. Brake control part should be adjusted according to the over-voltage protection setting. If the discharge resistor with over-temperature protection, it is recommended that, the control contact should be connected to the main control circuit.

7.2.4 Leakage current protector

Because safety capacitor or distributed capacitance to earth exists in interior of ac drive and motor and in the input or output leading wires, and higher carrier frequency is used for low noise, the leakage current of the ac drive is to high, obvious in large capacity machine. Sometimes, it may lead defective action of protective circuit.

If you encounter problems above, except lessening carrier frequency and shortening leading wire, you have to mount leakage current protector:

Mount leakage current protector at the input terminal (come after MCCB) Current action level (with ac drive) must be ten times more than the total leakage current (without ac drive) of circuit, ratio noise filter and motor, etc.

7.2.5 Capacitor Box

The capacitor box is particularly applied in the circumstance requiring continuous duty when the power-off is relative long (more than 20ms). You can order from our company, please specify the actual load, the required continuous duty time after power-off when you place the order, so that our company can prepare you the product. As the capacitance box may influence some parameters in your machine after it is assembled, the preparation by the user is not recommended.

Chapter 8 Maintenance



1. Terminals of the ac drive have high-voltage. Never touch them, or it will cause

electric shock. 2. Replace all protective covers before powering up the ac drive. When removing

the cover, be sure to shut off the power supply to the ac drive. 3. Turn off the main circuit power supply and verify the charge LED has lit off

before performing maintenance or inspection. 4. Only authorized personnel should be permitted to perform maintenance,

inspections or parts replacement, or you will risk electric shock.

CAUTION

1． The keyboard PCB board, control PCB board and drive board employs CMOS ICs. Do not touch the CMOS elements.

2． Do not connect or disconnect wiring or connectors while power is applied to the circuit.

3. Do not check signals during operation, or the equipment will be damaged.

8.1 Inspection and Maintenance Ac drive is a typical product, which combines the power electronics technology with the microelectronics technology. Therefore, it double features with industrial equipments and microelectronics equipments. The change of environment such as temperature. Humidity, smog and internal components aging factor will cause kinds of faults to the ac drive. For long time secure operation, daily inspection and regular maintenance (at least 3 or 6 months interval) is needed.

8.1.1 Daily Inspection

Before ac drive running, please check below: Whether Sound and vibration of motor are abnormal Whether heating of ac drive and motor are abnormal. Whether ambient temperature is too high. Whether load ammeter normal or not. Cooling fans are in normal operation. Brake resistors are with good insulation earth.

8.1.2 Regular Maintenance

The power supply must be cut off before regular maintenance. Only after the monitor has no display and charge LED has lit off 5-10 minutes can the maintenance begin. On the other hand, you will risk electric shock because there are storage capacitors within the ac drive that will hold charge even after the input power is disconnected.

The regular maintenance contents and cautions are listed in Table 8-2. Table: 8-2 The regular maintenance contents and cautions

Using different meters may get different result.

Please use moving coil. Voltmeter to measure input Voltage and bridge voltage meter to measure output voltage. Clamping ammeter is advised to measure input/output current and electro-dynamic power meter is the best instrument to measure power. If condition is limited, users can use the same meter to measure some times and take notes for comparison.

For waveform testing, the scanning frequency of electric oscilloscope should be more than 40MHz. For instant changing waveform, the Perfect frequency is over 100MHz. Please isolate the mains electrical supply before the testing.

When power supply is asymmetric seriously or three phases current is not balanced, please use electro-dynamic type three-phase wattmeter to measure the power.

Because the product has passed electric insulation test and dielectric strength examination, similar experiment is not required. In addition, the experiment will decrease the insulating voltage proof and improper experiment may cause product failure. If the experiment must be done, only skilled workers satisfy the qualification.

When doing experiment of main circuit voltage proof, please choose capacity equivalent instrument, using time and leakage current of which can be set. Moreover, this experiment will shorten life span of the device. Also, the main circuit terminals ( R, S, T, U, V, W, P1, + ,-)must be short-circuited before using megohm-meter and the megohm voltage level must match the system（220Vsystem/megohm-meter250V,380V system/megohm-meter500V,660Vsystem/megohm-meter 1000V. Control circuit can’t be measure by megohm-meter, but by universal meter (high resistance).

Earth-resistance of product (380V) should not be less than 5 MΩ and that of control



circuit shouldn’t be less than 3 MΩ.

8.1.3 Replace device at regular intervals

For security of the ac drive operation, to ensure the long term and reliable operation, the lifetime of components used in the ac drive must be periodically maintained. The lifetime of the component will be different because of the different environment and conditions. For constant operation, users can follow the next table to replace the device. In addition, the operation environment, load status and the current state should be considered.

Table 8-4 Parts Replacement Schedule

8.2 Storage and Keeping After bought in, the ac drive needs to be stored temporarily of secularly if it isn’t immediately: Environmental temperature should be in the defined range. Prevent it from being in contact with damp, dust powder, metal dirt; keep it in a draughty place. If stored period has exceeded one year, users should do charging experiment to recover the characteristics of electrolytic capacitor. When charging, please use voltage regulator to increase input voltage to rated voltage of the ac drive slowly and last the charging 1～2 hours. Experiment described above should be done at least one time per year. Voltage proof experiment will shorten life span of the ac drive. For the electric insulation test, please choose 500V megohm-meter, Earth resistance should not be less than 4 MΩ.

Appendix 4 MODBUS Communication


Appendix 4 MODBUS Communication This series of ac drive can perform serial transmission by using a programmable controller (PLC) and MODBUS communication. Composition of MODBUS Communication MODBUS is composed of one master PLC and 1 to 31 (maximum) slave ac drives. In signal transmission between master and slave units, the master unit always starts transmission and the slave units respond to it. The master unit performs signal transmission with one slave unit at a time. Hence, different address numbers must be assigned to each slave unit in advance and the master unit specifies a number to perform signal transmission. The slave receives the command from the master, performs the function and returns the response to the master unit. MODBUS Communication Specifications Interface RS-485

Start-stop synchronous Asynchronous, half-duplex Communication.

Communication parameters

Baud rate:200/2400/4800/9600/19200/38400 bps Data length: 8 bit fixed. Parity selection: EVEN / ODD / NONE STOP bit: 1 bit fixed.

Communication protocol In accordance with MODBUS

Maximum number of units to be connected 31

MODBUS Communication Terminals To use MODBUS communication function, please connect Terminal 485+, Terminal 485- to PLC. If there is more than one ac drive connected to PLC, the terminal resistance should switch at ON position as the following. ( The terminal resistance is only for model of 35R5GB/37R5PB and above models)

Note on Communication Wiring: (1) Communication wires must be separated from the main circuit and other power supply wires. (2) Communication wires must be shielded cable and one terminal near the ac drive the shielded layer must connect to the terminal GND of ac drive, the other terminal should keep free to avoid disturber. Sequence to Communication with PLC: 1. Cut off the power supply, Use Shielded Cable to connect RS485 terminal with PLC； 2. Power on the ac drive； 3. Use keyboard and set the communication parameters (P0.01, P0.02, P0.04, P7.00, P7.01, Pb.00～Pb.07)； 4. Perform communication between PLC and the linked ac drive.



MODBUS Communication Parameters Set To communication with PLC, the ac drive must be programmed. Here are some communication parameters that should be modified in advance. “”write-in is possible during running; “×”write-in is impossible during running but possible during stop.

* NOTE 1: Only select communication function of parameters: P0.01, P0.02, P0.04, P7.00, P7.01, can MODBUS（0001H-0004H）write-in message be accept by the ac drive Or the ac drive will response an error “02H”. * NOTE 2: If MODBUS Baud Rate and MODBUS Parity have been changed, the new parameters will not be effective until the invert power off and restart. The master and the slave must keep the same communication parameters setting. Otherwise, it is hard to make communication between them, or communication error. * NOTE 3: When the MODBUS Station Address of ac drive is zero, the ac drive will not accept the message that the master sends, even if the broadcast instruction. When the address has been changed, it will take effect at once. * NOTE 4: To be compatible with the ac drive of other series, Please select the unit of frequency reference carefully. If we set Pb.05= 1, the send value 01F4H will be equal to 50.00 Hz as frequency reference. However, if we set Pb.05=0, the send value 01F4H will be equal to 5.00 Hz as frequency reference. If we want to set frequency reference as 50.00 Hz, the message value must be 1388H. Transmission period limiting In order to cut down the packet loss rate caused by communication interference and to reach the optimum communication effect, please limit the transmission periods according to your need in the master station, thus ensuring the normal process of data transmitting and receiving.

5:38400 17ms 50ms *notes: In the way of choosing even parity checking, user can obtain the fastest communication response. The minimum transmission period is the interval between sending data from master station and receiving the correct data from the slave. If the transmission period is smaller than the minimum one, the master station is likely to receive disorderedly coded data. Format of MODBUS Messages When the ac drive communicates with master controller (Such as PC, PLC, etc.), the master send message to the ac drive and the ac drive sends an answer message to the master. The process or of MODBUS communication is like the right diagram description. As the MODBUS instructions are various, the content may be different. The distance between two MODBUS messages must keep the under mentioned time.

CRC check: CRC-16 is calculated as follows: 1. The initial value of general CRC-16 calculation result is "0", the initial value of the communication terminal is "1" (every bit of the 16-bit is "1"). 2. The LSB of the communication frame is the MSB of calculation result, the MSB is the LSB of calculation result. To calculate the CRC-16, switch the MSB and LSB. 3. The CRC-16 of the response messages must be calculated to be compared with the received CRC-16 of the communication frame. unsigned int CRC16(unsigned char*uptr, unsigned int ulenth) unsigned int crc=0xffff ; unsigned char uindex ; if(ulenth>=9)

ulenth=9; while(ulenth!=0) crc^=*uptr ; for(uindex=0; uindex<8;uindex++) if((crc&0x0001)==0) crc=crc>>1 ; else crc=crc>>1 ; crc^=0xa001 ; ulenth-=1 ; uptr++; return(((crc&0x00FF)<<8)|((crc&0xFF00)>>8));



Instructions example Read Holding Registers [03H] The contents of the specified number are read out in MODBUS address. The holding register contents are divided into the high 8-bit and low-order 8-bit, and become the data in the response message in that order. Example: Read out the slave 1 running status
